LINGUISTICS & CULTURE

I was reading an article from cnn.com entitled "5-year-old chimp beats college kids in computer game", but I got stuck in one of the paragraphs. I'd appreciate your help.
He thinks two factors gave his chimps the edge. For one thing, he believes human ancestors gave up much of this skill over evolutionary time to make room in the brain for gaining language abilities
What does "give sb the edge" mean?
Does "give up" mean "develop" in this context?
Thanks in advance!
